Breeding method through building pool in tidal zone

Abstract

A cultivation process by constructing pool in intertidal region, wherein an area similar the natural sea is constructed for providing a growth environment superior to the natural sea region, water drainage is proceeded everyday in the pool, and waves are formed during water inflow, which increasing the oxygen-containing volume of the water body, and culture excrement and old water can be discharged during water drainage. The cultivation investment needed by the process is less than other cultivation modes, and no contamination is produced.

Description

Technical field [0001] The invention relates to a new model of natural sciences, marine industry, and marine aquaculture. Background technique [0002] At present, the world's Shanghai aquaculture methods are at an advanced level in China. The main domestic aquaculture methods include tidal flat aquaculture, deep-water aquaculture, cage aquaculture, factory aquaculture, etc., and intertidal pond aquaculture, which has not been reported and used at home and abroad. [0003] The tidal flat aquaculture method has had a glorious life, but in the nearly ten years from 1993 to the present, the production of aquaculture has been declining, and many areas have no profits at all. Large tracts of tidal flat aquaculture ponds have been abandoned, because the fundamental failure of tidal flat aquaculture lies in turning the fresh seawater into a pool of stagnant water, and the seawater loses its ability to purify itself. The breeding of a large number of virus and bacteria endangers the life...

AI Technical Summary

Problems solved by technology

The breeding of a large number of viruses and germs endangers the life of the cultured animals. The breeding of viruses and bacteria and the oxygen consumption of the cultured animals worsen the deterioration of the water in the breeding pond, and finally lead to the failure of the breeding.

Deep-water aquaculture, because most of the cultured products are below 6 meters deep seawater, the breeding mode is naturally scattered, the natural loss of the cultured products and the invasion of natural enemies are very serious, and the harvest must have professional knowledge and special equipment to complete , the harvest volume cannot be fully harvested

Cage farming, due to the strong sea surface, is easy to damage the cages, affect the production of cultured animals, waste a lot of bait, make the finished product too high, and pollute the breeding sea area. In case of typhoon damage, all investment will be lost.

Factory farming cannot be promoted in a large area, the cost of farming is high, and there are many diseases
